Mechanistic Study of Visible-Light-Induced Photodegradation of 4-Chlorophenol by TiO2−xNx with Low Nitrogen Concentration
Figure 8
Normalized concentration profiles showing 4-CP degradation kinetics upon addition of SOD under Vis irradiation. Inset: DMPO spin-trapping ESR spectra under Vis irradiation in 4-CP/TiO1.979N0.021 ethanol solutions. Catalyst loading, 0.5 g L−1; 4-CP, 10 mg L−1; SOD, 10000 units; the DMPO concentration,1.6 × 10−2 M.
